This was excellent- but I love all of SInclair Lewis. Not as good as "Babbitt" though. Somewhat satirical, about a disaffected man whose wife never really loved him, convinces him to leave his working life in the US where he was a well-paid respected engineer, to practically live in Europe, while flaunting her affairs, etc. Good depiction of bleakness and depression and the emptiness and shallowness of much of life.
This is one of Sinclair Lewis' better novels, a good read.
